METHOD or nnrosrrrne SAND.

Lacasse. i

T all whom it m04/ concern Be it known that I, JACOB R. SnNsInAR, a citizen ofthe United States, residing at u Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in the Method of Depositing Sand, of which the following is a specification.

This invention relates to the method of depositing sand or the like and is fully describedin the following specification and shown in the accompanying drawings in which `Figure 1 shows the original level with the fiirst embankment thrown up;

Figs. 2, 3 and 4f show successive levels with the method or raising the embankment and applying the fabric facing thereto;

Fig. 5 is a plan viewshowing the method of reversing the fabric; and y Fig. 6 isa perspective view of the drain pipe.

In Fig. 1, I have illustrated a vertical cross sectional viewrof a trench 10 which is dug to form the embankment 11. A long strip of fabric 12 preferably canvas is then laid along the inner side of the embankment and over its crest. The purpose of this is to prevent erosionl as the height of the water rises on the embankment. A drain pipe having a vertical leg 13 and a horizontal leg 14 is placed on the ground so as to lead from a point just inside the embankment or area to be filled to a point beyond what is expected to be the outer edge of the :finished embankment.

As many of these drain pipes as necessary are provided and distributed around the area to be filled.

The drain pipe as shown in Fig. 6 is preferablyr made of boards and is opened at its lower or outer end, and as originally placed as shown in Fig.l 1, has the vertical leg 13 open at the front except for single board 15.

Tater and sand are then pumped into the area in front of the embankment, 11 until the water reaches the level of the top of the board 15 when it will flow out through the horizontal leg 14. This point is far enough away from the pump that the water is very calm and any sand or heavy sediment thereinA will gradually be deposited. This 'sand will eventually reach the level B of Fig. 2 when it will be nearly up to the crest of the embankment 11.

A new trench 10a is then dug in front of the old embankment 11,v thev sand being thrown over the topV of the old embankment forming a new embankment 11a. The front of the strip of fabric 12 is now uncovered but the upper portion of this strip is held between the old embankment 11 and the material forming the new embankment 11a. The lower part of the strip is then raised as shown by dotted lines in Fig. `2 and turned so as to protect the crest of thel new embankment 11a. This new position o f the strip of fabricis marked 12a. Y

A new board 16 isthen nailed to the Vfront of the vertical leg 13 of the drain pipe.

lfater and. sand are again pumped in until the sand'reaches the level C in Fig.l 3. A new trench 10b is then dug and the sand thrown over the top of the old embankment 11"L to form a new embankment 11b and the strip of fabric 12a is again uncovered. The lower part of this which extends between the embankments 11 and 11a is then pulled out and turned as shown in dotted lines in Fig. 3 over the top of the new embankment 11b to form a new protecting strip 12b. A new board 17 vis then placed on the vertical leg ofY the'drainl pipe and water and sand again pumped in, until the sand reaches the level D of Fig. 4:. A

A new trench 10c is then dug and the sand thrown over the top of the old embankment to 'form a new embankment 11C. `A strip of material 12" is again turned as previously described so as to form the protecting face y 12b. lThis may be carried on indefinitely until the sand has reached the desired height.

The great advantage of this method is that I am able to pump sand and water into an open space, deposit the sand therein and drain off the water without any danger of the sand itself being washed away.

While I have shown and described but a single embodiment of my-invention it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made which do not depart from the scope of the appended claims in which it is my invention to claim all novelty inherent in my invention as broadly as possible in View of the prior art.

vWhat I claim as new and desire to secure by Letters Patent is:

1. The method of depositing sand and the like which consists in forming an embankdown the inner side thereof to prevent it from eroding, placing a pluralityV of ,drains Y near said embankment leading outside said area, pumping' ii'ateiiand sand into said area, vdigging'out the sandV as-the fabricY becomes covered, frein the inner side of the lstrip of fabric, placingthis sand ontlie outer facev ofthe embankment and turning the. lower edge of the strip'of fabric o-vei the y this sandon vthe outer facevoftheA embanknewly inade top of the embankment.'`

T 2. `The method Vof depositing sand and the like which consists in forming an einbaiiknie'nt about the area to be filled, placing a strip of fabric longitudinally of the embankment, over the crest and extending .down the inner side thereof torpievent it from eroding, placing a plurality of drains near said embankment leading outside said area, pumping Water-and. `sand into 'said area, diggingl out the sand asthe fabric be- Acomes covered,'fro1n the inner side of the strip of fabric, lplacing this sand on the outer face of the embankment, turning theV lower edge of the strip of fabric over the` consists;in''diggingl a trench along the in- Y ner 'side of the dike, piling the materials()l reniovedpaiiallel to'and adja Vent the trench, placing a stripof fabric longitudinally along the inner Yface ofthe dike, digging out the sand as- J(he fabric becomes covered, from the inner sideofthe strip. of fabric, V placing nient and turning the lowers-edge of the strip of fabric over the-newly niadetop of the embankment. Y i

l. Themetliod of depositing sand and the like which consists in forming an embankment inclosing a givenlarea, pumping'a niiX- v ture of sand 'and Water into said area cariying a drainrpipe froinsaid area to a point outside and raising'the inlet Vend off-said pipeas the level ofisand in :said area is` raised by deposit, whereby sand is depos-V ited in said, arealand Water substantially free frein sand is drained off.
